Level up your Agent’s Expertise fast and easy!
Expertise Leveling in Division 2 is a boosting service that raises your Agent’s Expertise rank, one of the core progression systems in the game. Expertise defines how many upgrades each gear piece can hold, directly enhancing combat effectiveness. To increase it, you must gain proficiency with a wide range of weapons, armor, and gear sets — a process that normally demands extensive grinding across missions and activities. With this service, our boosters handle the routine, ensuring your Agent reaches the desired Expertise level quickly and safely, with all necessary proficiencies unlocked along the way.
Expertise progression unlocks the ability to apply upgrades to every proficient item, making builds stronger and more versatile. The current cap of 27 Expertise allows 27 upgrades per item, giving a decisive advantage in end‑game activities such as raids, missions, and PvP. Achieving this requires proficiency across hundreds of items, which is highly time‑consuming. KingBoost eliminates the grind, delivering a fully optimized Agent prepared to perform at the highest level.
Boosting is carried out safely and transparently by our professional team. You can choose your platform — PC, PlayStation, or Xbox — and select the completion speed that suits you best: Normal, Express, or Super Express. KingBoost is trusted by thousands of players worldwide, delivering secure, manual boosting with maximum attention to detail. You get the exact Expertise level you want, without risk or unnecessary delays.
50,000+ players trust us. That number isn't luck—it's the result of years of consistent delivery, professional boosters and a support team that cares about your experience.

Amazing service, prompt and no complaints at all.
very fast and friendly
I’ve been a customer of KingBoost for several years now, and I’ve had nothing but positive experiences. Whether it was Delves Nemesis, Mythic+ or Raids, everything has always been handled professionally and smoothly.
The staff is consistently friendly, polite and helpful, and the support team responds very quickly whenever I have a question or need assistance. Communication has always been clear and straightforward, which makes the whole process easy and stress-free.
I also think the prices are very fair for the quality of service provided. Over the years, I’ve used KingBoost for different types of content and have always been satisfied with the results.
I honestly can’t say anything negative about my experiences so far. Great service, friendly people, fast support and fair prices. I’ll definitely continue using KingBoost in the future and can highly recommend them!

A VERY honest review.
I've used G2G, Playerauctions, and Kingboost.
I've been a top player in WoW when it comes to arena and raiding. How? I paid for it. That's why this is going to be posted as anonymous. I've spent THOUSANDS of USD getting top on the Blizzard and Raider io leaderboards via M+ and raiding, and I've used all three of these sellers.
G2G: I actually argued with a few sellers over what I wanted in a boost. I'm the one paying, I should have it tailored. If you're not buying cheap Discord nitro's from G2G, avoid. I never could make a deal with any of them. Plus, I've dealt with a lot of rude sellers.
PlayerAuctions: TBH Asian slop. I have nothing against Asians, but they can't sell for crap let alone most of the time I don't understand their poor English. I've had a few ghost me a few times. I suppose they thought I was being too complicated about what I wanted. Sorry, if I am buying a service, I want that service the way I want and YOU WILL do it how I want or I refuse to buy your service. However, I mainly use PlayerAuctions to buy WoW gold, it's a very simple process and they at least understand that; also it's very cheap.
Now let's talk about Kingboost. I've dropped over $1200 so far on KB. $400 of that was to get worlds top in arena when the season came out and now I'm buying boosts on other MMOs I'm playing. Here's what I LOVE about Kingboost; they're Russian. Why is that a thing? Well, they actually understand what I want unlike PlayerAuctions. It shows effort to understand and communicate to the buyer. It's very nice when both parties can fully understand another. I also cherish their occasional generosity. I had a booster once give me a bit more than what I bought because they were feeling generous. Will this happen to you? Maybe, maybe not, but I felt appreciated. The customer service, I'm pretty sure there's two of them that alternate, have been extremely nice and thoughtful of me. I've even had some bad days and they were right there. They also go beyond to make sure that you're happy. I've never experienced that before with any other service. It sorta feels like they're a friend. Kingboost may not be the cheapest service, but you're buying quality and that, to me, means the most; because spending your money and dealing with frustration, is fear. With Kingboost, when I spend money, I sleep well knowing my account is safe and Kingboost won't hurt my account or take off with my money (which has happened on G2G once.)
So, take my experience and use Kingboost. No service is perfect!!! Let go of that illusion. Sometimes Kingboost has day or two wait to find a booster for my order, but the boosters are quality and I've delt with boosters on every seller market. Hell, by this point, I have my own boosters that I wait for to become available. I've used Kingboost THAT MUCH over the past 2 years. Again, Kingboost isn't slop. It's quality.
Very fast and efficient great job!
